Abstract: 1,043,598. Loading agricultural vehicles. M. ESCHLBOCK, and R. ESCHLBOCK. July 26, 1963, No. 29692/63. Heading B8E. [Also in Division A1] An implement for loading and transporting grass crops comprises front opening loading trailer, the loading surface of which consists of a plurality of individually lowerable elements which are at least partly flexible and are detachably connected to the trailer. In the embodiment of Fig. 2, the trailer has two wheels 4 and a towing fork 11 by which it can be towed in the loading position shown or on the wheels 4 only for road transport. The grass is fed into the trailer through a front side opening 37 by a chain rake 43 receiving material from a cutter or pick-up device. The floor of the trailer consists of wire ropes 25 attached to a cross-beam 26 and detachably to a winding core 22. The arrangement is such that with the ropes 25 loose as shown the stubble will, as the trailer is drawn along, urge the material towards the rear wall 17, but when the trailer is to be driven to the delivery station the ropes are tightened as by a lever 29 to raise the load off the ground. To unload the trailer the ropes are detached from the core 22, the rear end 17 is swung clear and the trailer is driven away, withdrawing the ropes from under the load. The ropes 25 may be replaced by thin rods or metal strips or in the modification of Figs. 8, 9, by longitudinal boards 70 pivoted to the frame 71 at 72 and held horizontal by chains 74 hooked to one board and connected to a tensioning lever 78.

Title: Improved control systems for electric motors
IPC: H02P7/26
Filed: 1956-09-28
Abstract: 842,446. Control of D.C. motors. GENERAL ELECTRIC CO. Sept. 28, 1956 [Sept. 28, 1955], No. 29704/56. Class 38 (3). [Also in Group XXXV] A thyratron D.C. motor control system has variable limiting of the error voltage applied to the thyratron phase-shift control, the limit depending on the instantaneous motor speed and current. The armature 10 of a D.C. motor, having independent constant field excitation, is supplied from transformer 37 through thyratrons 28, 30 for forward rotation or thyratrons 34, 36 for reverse rotation. Speed control by phase-shift of the A.C. bias on the thyratron grids is determined by the algebraic difference between motor B.E.M.F., derived from potentiometer 15, and a speed reference signal applied to input 18, 19. The amplified difference is applied as a push-pull voltage to twin-triode cathode followers 23, 23a whose outputs feed the phase-shift devices 24, 24a, either one of which is functioning at a particular instant. To prevent excess power being applied to the motor the control grid voltage of valves 23, 23a is limited by shunt diodes 39, 40. The voltage at the cathodes of these limiters is made proportional to motor speed, i.e. B.E.M.F., with an auxiliary dependence on motor current from the voltage across capacitor 59, this compensating for IR drop in the armature. The difference voltage on potentiometer 43 is applied to the limiters via twin-triode phase splitter 45 and twin-triode cathode follower 50, 53. If the maximum speed reference signal applied, the resultant error signal is greater if the motor is only running at low speed than if it is running fast. The extra degree of limiting necessary under such conditions is provided by means of the reduced cathode voltage on the diode limiter which corresponds to the lower speed. Thus the limiting action varies as the speed; the effect of armature current on the limiter system is that of inverse variation. An alternative embodiment is described which omits the IR compensation circuit 56, 57, 58, 59 (Fig. 1 (not shown). Specification 828,166 is referred to.
